MEANS FOR ANCHORING NIPILES.

Specification of Letters Patent.

Application filed August 5,1913.

To all 'whom it may] concern lieI it known that l. AN'roN Sonnen MANN, a citizen ofA the United States, residing at Decatur, in the county of Macon and State ot' Illinois, have invented new and use- ;tul lmmovements in Means 'for,rinel'lorinfVr Nipples, ot which the following is a specification.

Thi@I invention relatesv to improvements in ineans 'for anchoring a fitting in a pipe 01' the like.

The invention is designed chiefly to provide moana for securely anchoring nipple in a pipe or other article, the wall oli which is So thin that it does not'I aftlord sutiicient masa lior ordinary screw-threaded connection of the nipple therewith, hut is not'restrieted to the anchoring of nipplea, as it :is useful in the attachment ot cocks and variouI fittings to pipes, all of which are included inthe following description under the generic'term fitting.

The invention consists in the means hereiinatter described and claimed, reference heing had to the accompanying drawing which allowsI the preferred elnlnidinient ot the invention, and in which liignre 1 ia a view, chiefly in longitudinal section, illustrating the niplile-end expanding-tool in side elevation, the end ot' the nipple heing Shown with 'its end expanded to anchor the nipple. li`ig.`2 is an end view looking toward the exljiander end ot the expanding tool, as arranged in Fig. l, with the -wall ot' the pipe, omitted. Fig. f3 is a View similar to Fig. 2 showing the expanding tool rotated to a ditlcrent position so that it may he passed, together with the sleeve in which it' rotates, through the nipple either preparatii'n'y to or atter complet-ion ol the anchoring` operation. Fig. Jt is ay perspective View ot.l the expanding tool` Fig, 5 aperspective view ot the sleeve in which the exlianding tool is arranged 'tor rotation during .wperatzion. hig. o i.-; an end view ot' Said sleeve. Fig. '7 shows, in perspective, nuts hy which the expey ling-tool earryirig-sleeve is held in proper "oaition in the nipple. Fig. t5 shows, in perspective, wrench grips to he fitted to the expandingtiool shank for operation ot! said tool. Fig. t), an end view of the parte shown in ltig. 1, vlooking at the right-hand end of said figure. In the drawing, the reference numeral 1 designates, as anexample of one o'tf the n- ]faten t ed Dec. 2, 1913. Serial Not 783.205.

tended uses ol? the invention, a fragment of a thin-walled pipe, such as a ealamine pipe, having a screw-threaded lapide-receiving opening 2.

El designates a. nipple which. as illustrated, has had its end, within the pipe7 expanded t'or secure anchorage. lhia` nipple is provided with Acrew-threwis: to engage those of the opening i) ol the pipe, and its end projects within the pipe, as lahown. The opposite end ot the nipple is Screw-thrtanfleil, aa shown at ft rthe numeral 5 designates a sleeve which is inbertihle into and removahle t'rom the nipple, and which is designed to have a nice tit within the nipple. l"er the operation ot anchoring the nipple, thissleeve if.- dcaigned to he held 'in position in the nipple against endwise movement, with its end slightly within that end oth the nipple which is to he expanded, and l have shown one auitahle way for so positioning and holding the Said Sleeve, which consists in rn'oviding the same with an annular collar (5, that' resta against an interior Shoulder 7 with which a nut S adapted for engagement with the scre\\'-tlneads ft of the nipple is provided, and against which slnmlder the .aaid collar is clamped by means ol the clamping nut i). 'lhe Sleeve 5 is provided with an expandingtool-shank receiving-llore 1t) which, as shown, is eccentric to the longitiulinal axial line ot the Sleeve, as liest shown in Figs. 5 and t3 ol the drawing. 'lhe object otl this eccentric arrangementot' the horc is toenahle the.cxpaInling-tool to he. together with s-faid sleeve, inserted into and witlnlrawn Vtrom the nipple aS will clcart' appear hercinat'ter.

l'hc sleeve 5 is provided with a pur-lier Il, one edge ot' which, t?. eonatitntes a atop or gage against which the \\".\rl ing 'tace IN or the hercinatier-ihecriherl expander head i5 cometo rest. a1- ho\\n in l=`igx 2i. in which position the expanding-tool and the f-lcevc nay he infartcd in er witlnlrawn tronllhe nippic. 'the oppoaitc edge Il oli the pusher ll constitutca` an impeller. When the wall li' ot' the expander-heini ia engaged therewith, as :drown in Fig. Q. and the Ialeeve is rotated in the direction hewn hy the arrow in said Fig. if, the iinpeller constitutes a .link or coupling hetween the sleeve and the expander head. and causes the expander head ot the expanding tool to rotate in unison with the rotation of the lQleevc. This is the preferable arrangement, hut it will be obviens that this rotation of the expandingtool and its head in unison with the rotation of the sleeve, may be accomplished by an implement which would simultaneously engage the wrench grip 2O and the wrench grip 23, in which event the-pusher 11 could be omitted.. It is also obvious that the operation could be carried on by applying one wrench to the wrench grip 2O to hold the sleevefroni rotation, and another wrench to the wrench grip 23 to rotate the expandingtool within and independently of the sleeve.

The expanding-tool comprises a shank 14 which is insertible into, rotatable in,and withdrawable from the bore of the sleeve 5, and gis provided with alaterally extending expander head 15, having two wedge faces one of which, 16, is peripheral and inclined or oblique with relation to the axis of rotation of the tool, and the other, 18, of which is substantially tangential to the periphery of the expander-head. Y

Beyond the collar clamping-nut 9 angular formation is imparted to the sleeve 5, for example, as shown at 19, and a wrench- 1 grip 2O corresponding in contour to the angular part of the sleeve 5, as best shown in Fig. S, is removably arranged upon said angular' portion. Manipulation of this wrench-grip will cause the sleeve to rotate, and, when thepusher 11 is in engagement with the expander-head of the expanding tool, as shown in Fig. 2, will cause said expander-head to revolve around the axis of rotation of the sleeve, and operate as hereinafter described.

As shown in Fig. 1, the shank of the expanding tool portion 19 of the sleeve, and adjacent this angular portion of the sleeve the Said shank is in angular formation, as shown at 22, to receive a wrench grip 23 which is independent of the wrench grip 20, and .may be slid onto and oft of the angular portion 22. Manipulation ofthis wrench grip causes the expanding-tool to rotate within the sleeve upon its own axis, and thus project its peripheral wcdge-facel beyond the outer circumference of the sleeve into expanding engagement with the end of the nipple. rl`he exti-'eniity of the shank of the expanding tool opposite the expander head is screw-threaded, as at 24, and a bilnling-nnt 25 is fitted thereupon and made to engage the wrenchgrip 23, thus holding the latter, as well as the ,wrencl'i-grip 20, in operative position, as shown in Fig. 1. The wrench-grip 23 also, as shown. in Figs. 1 and 9 of the (,lrawing, engages the end ot the sleeve 5 and thus holds the sleeve with its collar (3 seated against the shoulder 7 of the nut 8., .The .said binding-nut not only serves to hold the wrench-grips 20 and 2?) in operative position, but also holds the expander-head to' its work of expanding the end ofthe nipple,

projects beyond the angularv The mode of operation of the invention, 1

and one suitable way of assembling the parts for such mode of operation, will be sufiicient, together with the foregoing description of the several elements of the apparatus, to enable those skilled inthe art to fully understand the invention. Assuming a nipple-receiving opening 2 has been tapped yand sercw-threa ded in a pipe or the like; first, the expanding-tool may be fitted in the eccentric bore of the sleeve 5 with its tangential wedge-face 18 in Contact with the stop-face 12 of the pusher 11, as shown in Fig. 3 of the drawing, so that the expander-head lies within the circuit of the interior of the wall of the nipple to be anchored. The sleeve may be then fitted into the nut 8, with its collar 6 resting against the shoulder 7 ot the nut, and the confining nut 9 adjusted to position as shown in Fig. 1. Then the sleeve may be inserted into the nipple and the nut 8 made to engage the screw-threaded end 4 ofthe latter, after which the wrench grips 20 and 23 are slipped into place and the binding nut 25 is adjusted. The nipple, with the contained sleeve and expandingtool, is then manually screwed into the opening 2 of the pipe as far as it may be conveniently done manually, and thereafter by means of a wrench or other suitable implement applied to the nut 8, which may be suitably fashioned for the engagement of such implement, as, for example, provided with wrench-grip faces 8, as shown in Fi g. 7, the nipple is screwed home in the opening 2. (.)f course, the sequence of steps of assembly ot parts just stated is illustrative merely, and said parts may be otherwise assembled to assume the cooperative relation shown in Fig. 1 of the drawing. The parts are now inposition to accomplish the exanding ot the end of the nipple within the wall of the pipe. A wrench is applied to the wrench-grip 20 and firmly held to prevent rotation of said grip, and consequently of the sleeve 5, and at the same time the expanding tool is rotated upon its own axis in the direction indicated by the arrow in Fig. 3 by means of a wrench applied to the wrench-grip This causes the I ieripheral wedge-face 1G of the expander-head to be projected into engagement with the wall of the end of the nipple and gradually and progressively expand the same until the edge 17 of the expander-head comes intov engagement with the edgel of the pusher 1l, which limits the rotativemovement of the expanding-tool in this direction. It is obvious that turther rotation thereof, if possible, would merely operate to retract the expander-head from the wall of the nipple. When the parts have assumed the last described position, which is illustrated in Fig. 2 of thedrawing, the wrench is removed from the grip 23, and a wrench applied to few revolutions oi the expaiuler-head wilt be su'tlicient to complete the operation, after which the expander' head may be reversely rotated through the medium ot a wrench applied to the grip 23 until it comes to rest, as shown in Fig. 3, against the stop i2, aftery which the several elements ot the apparatus may loe disassembled, for example, b y ro-y tatingthe nut 8 until 1t is 'free of the screwthreads 4 of the nipple, whereupon all theA parts, including the sleeve and the expanding tool, may be withdrawn, leaving ther nipple anchored in place.
